Lenovo X1 Carbon 20BT shutdown automatically

Hey guys,

I have Lenovo X1 Carbon 20BT with Windows 10 Pro x64 v1809 installed. Some minutes ago it auto shutdown. I thought battery is dead so plug in the charger and tap the power button but it had 27% battery left also.

Regards.

Overheating? Try CPUID HWMonitor to check temps.

Also try generating a diagnostic system power transition report by running this from a Elevated Command Prompt:

powercfg /SYSTEMPOWERREPORT

Output will be %userprofile%\sleepstudy-report.html. Open that in your web browser, see if it tells you anything useful.

Yes there was abnormal shutdown check the attachments.

Rats, doesn't give a clue as to why though. Try hwmonitor then. Also look in Event Viewer and check Reliability Monitor: How to View Reliability History in Windows 10

On HWMonitor all temps are fine and not overheating.

Have you seen your PC shut down suddenly more than once?

It only happened once.
